About Costa Nossa
Costa Nossa is Sesimbra's highest-regarded restaurant, commanding sea views and a casual-yet-refined atmosphere that welcomes everyone from families to solo diners. The modern, airy design pairs with the kitchen's exceptional local seafood—langoustine rice, Sesimbra shrimp, and crab feature prominently—executed with technical precision and respect for raw materials. Service is the defining strength: staff anticipate needs without hovering, greet guests as friends, and navigate language barriers with patience and warmth. The wine list is curated with care, balancing regional Portuguese selections with international depth, and sommelier recommendations consistently earn praise. Desserts (chocolate mousse with toasted flour, thousand-layer rice cake) and coffee round out an experience that feels both accessible and aspirational. Dogs are welcome on the terrace; ample parking (covered and uncovered) removes logistical friction. Reviewers across languages and backgrounds describe the experience as transformative—not just a meal, but a moment of genuine hospitality.
Costa Nossa is built for lingering — the coffee is a destination in its own right, and the atmosphere encourages staying for a second.
In the last 90 days, Costa Nossa has drawn 22 substantial written reviews (50+ characters of genuine feedback) — recent momentum that is one of the signals behind its place on the hot list.

Langoustine rice, Sesimbra shrimp, and crab consistently praised as among the best ever tasted; kitchen works with premium materials and technical precision.
Anticipatory, warm service
Staff greet guests as friends, intervene at exactly the right moment without being asked, and handle non-Portuguese speakers with exceptional patience and attentiveness.
Curated wine list
Described as 'vast and discerning' with sommelier recommendations that enhance the meal; wine pairings and sangria selections earn specific praise across reviews.
